docs

docs is a skill for Claude Code, Codex from nrl-ai/chub. It costs 23 tokens per session (126 once invoked), scanned A, original, MIT.

A documentation lookup tool for finding or retrieving programming-library documentation from the Chub registry.

In plain words
What is it for?
Use it to search documentation by topic or library name, or retrieve a particular entry by its ID.
Why use it?
It avoids searching through scattered documentation and lets an agent fetch a specific library entry directly when its identifier is known.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Documentation Lookup

Look up: $ARGUMENTS

If the input contains / (e.g. serde/derive), use chub_get to fetch it directly. Otherwise use chub_search.

After fetching, check chub_annotate (read mode, no note) for any team-recorded issues or practices on that entry.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
